SLATE-DRESSING MACHINE.

SFECIFICATION forming part of Letters Patent; No. 327,811, dated October6, 1885.

Application filed July l1, 1385.

To LZZ whom it may concern:

Be it known that I, ADAM H. MEYERs, a citizen of the United States,residing at Melmorehin the county of Seneca and State of Ohio, haveinvented certain new and useful Improvements in Slate-Machines; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertaius to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

Figure l of the drawings is a representation of a front elevation. Fig.2 is a vertical section on line w, Fig. 1. Fig. 3 is a horizontalsection on the line y/ y, Fig. l. Fig. 4 is a horizontal section of theline z z, Fig. l.

My invention relates to machines for punching nail-holes in slateshingles, and at the same time trimming or shearing the shingles to givethem the desired angles; and the invention consists in the constructionand novel combination of parts, as will be hereinafter fully described,and particularly pointed out in the claims.

Referring by letter to the accompanying drawings,A and B designate twoparallel basesills, which are connected at their rear ends by across-sill, B', to give them stability.

C and D designate auxiliary sills or notched clamping pieces, which restupon and are bolted to the upper faces of the primary sills A and B, andpartially embrace the lower ends of the uprights E E' of the frame andhold them firmly in place on the base-sills. These uprights E F/ areprovided with elongated vertical slots G G, which extend from about themiddle of their heights to their npper ends. The uprights E E' areconnected at their upper ends by a stringer or girder, II, havingdepending end pieces, H', which abut against and are secured to theouter faces of the uprights E E'.

To the under faces of the girder H' are secured blocks I I, which abutagainst the inner faces of the uprights E E' and give additionalstrength to the structure.

At a proper height above the base-sills the uprights E E are provided ontheir inner Serial No. 171,359. (No model.)

faces with rearwardly-extending arms J J', which latter are provided ontheir inner faces, at their rear ends,with bearings J 2 J 2, for the`journals J3 Ja of the treadle-arms K K. The connecting-rod K', betweenthe lower ends of the treadle-arms K, Vis provided with a spool orfoot-piece, K2, and the treadle-arms K K coil once around their journalsand extend forward and upward and connect with the lower ends of thevertical draw-rods L L. The draw-rods L L pass up through the slot issecured to blocks M', which are in turn secured to the inner faces ofthe uprights E E', so that the upper edges of the blocks M' come justbelow the lower ends of the elongated vertical slots G G.

Upon the horizontal stationary bar M is secured the horizontaladjustable frame N, by bolts N N', passed up through the slot L', andthrough elongated slots N 2 in the parallel arms Ns N3 of the frame N,and provided with securing-nuts N4 N", to hold said frame N to itsadjustments, which are horizontal either back or forth, and at rightangles to the slotted stationary bar M. At their forward ends theparallel arms N 3 N 3 are connected by two transverse parallel arms N 5N5, having a space, N, between them, through which the material punchedfrom the slates falls. Upon these two parallel arnis N5 N5 are securedtwo adjustable anvils, O O', having their punchholes O2 O2 rectangularin outline at their mouths or upper ends and circular in outline attheir lower or discharge ends.

Attached to the outer side of the anvil O' is a guide-plate, P, againstwhich one straight edge of the sheet of slate is placed in position for,clipping and punching the same.

Upon the horizontal bar M, between the arms of the horizontal adjustable frame N, are secured the lower blades, Q Q', which converge fromthe front toward the rear, and to the same bar, at the middle linebetween the converging blades Q Q', is secured a hinged horizontal arm,R, having a slotted adjustable angular slide, R', secured upon its upperface, which serves as a stop for the forward end of the slate when inposition to be clipped and punched.

Above the stationary horizontal slotted bar L' in the horizontal barM,which rests on and IOO M, I provide a horizontal longitudinallyslotted sliding bar, S, which is secured to the lower end of a verticalguide-stem, S, which latter works through a bearing, S2, on the girderor top rail of the supporting-frame, and is provided with a removablehead, S3, held in place by a set-screw, S4. The stem S is held in andreturned to its normal position by a coil-spring, S5, interposed betweenthe bearing S2 and the removable head S3. The bar S is provided with endprojections, T T, which enter the vertical slots in the uprights of themain frame and guide the sliding bar S in its vertical movements.

On its under face the slotted sliding bar S is provided with the upperpair of converging blades or 'shearing knives, U U, which are providedon their backs or upper edges with threaded studs U U', which pass upthrough the slot S in the slotted sliding bar S and are secured in placeby nuts S7 S7.

Upon the upper face of the slotted sliding bar S are secured the slottedadjustable arms V V,which are held in place thereon by bolts V V andnuts V2 V2. At their forward ends these adjustable arms V V are providedwith the vertically-depending punches V3 V3,which are cylindrical incross-section, tapering from above downward, and are pointed at theirlower ends, and are located directly above the anvils O O', so that whenthe punches V3 V3 are caused to descend, by using the treadle they willpass through the slate,when in place, and enter the punch-holes OZ O2and drive the material to be punched out through the punchholes O2 O2.At the same time that this operation is being performed the upper pairof shearing knives or blades will descend with the slotted sliding beam,and the sheet of slate resting on the lower pair of blades will be cutor sheared between the two sets of knives to present the desired anglesat one end upon the sides ofthe slate. As soon as the pressure isremoved from thetreadle, the coil-spring, which has been compressed,will expand and raise the slotted sliding bar M, and with it the upperpair of blades or shearing-knives.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is

l. In a slate-dressing machine, the combination of the main frame havingthe verticallyslotted. standards, the longitudinally-slotted transversebar M, the shearing-knives, and l hinged bar carrying the adjustablestop arranged thereon, the horizontally-adj ustable frame N, carryingthe laterally-adjustable anvils, the uppei` vertically-moving barcarrying the punches and shearing-knives, and the draw-rods connectingthe said bar with the treadle, substantially as specified.

2. In a machine for trimming and punching slate, thehorizontally-adjustable frame carrying the laterally-adjustable anvilsand trimming-knife, and adapted to serve with a main frame having aslotted beam, as M, substantially as specied.

3. The combination, with the main frame having the vertically-slottedstandards and the rearwardly-extending arms J J, of thelongitudinally-slotted bar S, moving in the slots of the standards andcarrying the adjustable shearing blades and punches, the treadle, anddraw-rods connecting the treadle with the said moving bar, substantiallyas specified.

4. The combination, with the main frame, of the stem S', passing throughan aperture in the top bar thereof and surrounded by a spiral spring,the vertically-moving bar S, secured to the lower end of the said stem,the cutting device, the treadle, and draw-rods connecting the treadlewith the vertically-moving bar, substantially as specified.

5. 'Ihe combination, with the main frame having the vertically-slotteduprights and the slotted stationary lower horizontal bar, the hingedstop, and the adjustable covering, knives arranged on the said bar, thelongitudinally-slotted vertical slide-bar, its adjustable puncharms,withpunches, ofthe verticald ly-arranged spring-actuated guidestem passingdown through the top beam of the main frame, and draw-rods connectingthe hinged treadle with the vertically-moving slotted bar, substantiallyas speciiied.

6. The combination, with the longitudinally-slotted transverse-stationary bar M, provided with the rear hinged adjustable stop, R, ofthe horizontally-adjustable frame provided with the adjustable anvils,substantially as specified.

In testimony whereof I affix my signaturein presence of two witnesses.

ADAM H. MEYERS.
